AI Technical Summary
Technical Problem
然而，现有技术中采用游标卡尺进行测量模型盲孔的尺寸时，由于盲孔的底端为圆锥角，导致游标卡尺不方便测量，并且存在不同工作人员的测量结果不同的情况，都导致盲孔尺寸的测量误差较大，影响模型的制作
Benefits of technology
[0012]与现有技术相比，本实用新型的有益效果是：通过在测量杆上设置测量凸起，并将其相对于杆体倾斜设置，使测量凸起能够准确插入异形孔中，从而实现了对异形孔高度的精确测量，克服了现有技术中缺乏对工件内部高度值的准确计算功能的问题，显著提高了测量精度；通过旋转部的设计，方便安装；测量部的设计能够直接测量内凹形零件的内凹底层厚度，无需额外测量外壁厚度和内凹深度的差值，大大简化了测量工序，提高了测量效率，同时减少了测量误差。
